SPECIFICATION forming part of Letters Patent No. 278,448, dated May 29, 1883.

To all whom it may concern:

ot which the following is a full,c1ear, and exact description,referencewbeing had'to theaccompanying drawings, making part of this In the dra-wings,iFignre l is an end view of a machine embodying my invention. Fig. 2 is afron'tview, and Fig. Sisa plan of the same machine. Fig. etis an endviewot'the im proved "rolleriand roller-chair, showingalso' the chairplan}: and a part of the table-top in section, andalsotheman'ner of securing the-chair to the chair-plank. Fig. 5 is a .fron'tviemaud. Figotia planyot' thechair. Fig. .7Qis a transverse vertical section of chair-plank through the center of the chair-seat. Figs. Sand!) are longitudinal vertical sections of my improved presser hand-roller, showing. two lorms and i llustrating twomethodsof prod ucing the same. Like letters in the drawings "refer to li ke parts of theinvention.

Much ofthe straw-board usedintthe manufactnre of paper boxes, as well asotiother similar board usedin the arts, iscovered orrlined with paper while in thesh'eet. Hitherto the various appliances and methods 1 em ployed iin lining orcovering suchboardwith paper have beencomparatively expensive and unsatisfactorybecause of 'the'timeand labor required in the operation. a l

Theobject of myinvention isto provide improved devices by the employmentof which less time and labor will be required in lining sheets of straw or other board. My invention consists of the combination, with asuitable table'provided with a verticallyprojecting position-gage, of aroll'erand rollerchairs; and, further, consists of an improved hand presser-roller, and also of an improved hand presser-roller chair, and of certain details of construction hereinafter described.

Adsifi suitable table, which may be of wood andabout three feet wide, six feet long, and thirty-three inches high,'orof any-other suit able dimensions and material. The upper surface of the table A if of wood, may be neatly covered with sheet-zinc, turned down over the edges to protect the wood from moisture. A

Application filed August 16,1882. (No modeLi in the drawings represents such a wooden ta ble covered with zinc.

B is the vertically-projecting position-gage,

O is the hand presse i roller,which should be .somewhat longer than the board "to be lined, and which consists, essentially, of a smooth cylinder, of suitable length, diameter, and weight, to be rolled by hand forth andback over the board to belined, pressing the said board against the underlying lining-paper.

table-top, considerably thicker than the rest of 'that top in that part of its length over which the roller rests. The upper surface of that part of the chair-plank which is under the roller hastheform'of the chain seat a, and is virtually a continuation of that seat. The upperpart of the inner edge of the chair-plank forms, with the innerface of the chair, a continuous positionfgage, B. The roller-chair is screwed in its seatin the chair-plank by screws c,a.sshown in the drawings.

The dotted lines (1 in Fig. 3 represent the length and breadth and position ot a sheet of straw or other board to be lined.

Sheets of lining-paper of the same length and breadth, in number sufficient to make with one sheet of board a thickness of about three-eighths or one-half an inch, are placed on the table- -one exactly above the other-with one edge against the position-gage B and the two or more short vertical'faces serving the :same purposes.

other edges over the dotted lines d. The optube, of suitable length and diameter, into erator then dips his brush in the paste-bucket, spreads the paste evenly over the upper surface of the topv sheet of lining-paper, nextlays the sheet of straw board v carefully on the pasted surface of thelining-paper, being careful, with the aid of the gage B, to make the edges of the board coincide with the edges of the lining-paper. The roller 0 is then immediately pushed from the chair D, rolled rapidly out to the extreme edge of the sheet of board, and as rapidly back to the chair. The sheet'of board smoothly lined with the adhering paper can then be removed and the operation repeated with a second sheet of board and the next sheet of lining-paper.

The chair D, as represented in the drawings, is of cast metal, preferably iron, is intended for use in pairs or in sets of more than two, and when so used constitutes a combined chair and position gage, D B, which may be placed on the edge of any suitable table-top without the employment of a chair-plank, F, thicker than theother portions of said top.

The chair-plank F may be used in combination with a stout strip of wood, or with strong nails, or with any device whatever which will stop the roller 0 and cause it to drop into a depression in the upper surface of the said chair-plank, the said devices thus constituting an equivalent for the chair-back a.

The under side of roller 0, when in its seat a, should not be less in height than is the top of gage Bsay onehalt' of one inch above the general surface of the top of table A. The

projecting ridge 9 should be sufficiently high to act positively in retaining the roller 0 in its seat when rolled back from the board. An

inclinedplane, It, should connect the top of ridge 9 with the top of gage B, to facilitate both the coming back and going forth of the .roller 0.

-'light.

For ordinary purposes in a-paper-box factory the roller 0 should weigh about forty-five tral part of its length, orl make it of light material loaded in the middle. Figs. 8 and 9 in the drawings represent such a construction of roller D. The former represents a boilerwhich, at a suitable distance from each end, I drive wooden plugs 'i,'the intervening space between the plugs t being filled with iron borings or turnings moistened with a solution of sal-ammoniac and water. Fig. 9 represents a roller of cast-iron hollowed at each end and solid in the middle, turned on the outside in a lathe, and so proportioned as to give the desired length and diameter and weight. Roller D may consist of a wooden roller wit-h a central hollow filled by a bar of iron or other metal to give the required weight. c

Having thus described my.in'vention, what I claim as new, and desire to secure by Letters Patent, is- 1. In a machine for lining straw and other board, the combination, with the table A, of the vertically-projecting position-gage B, for gagingor determiningthe position of the board jecting position-gage consisting of two or more cast-metal chairs, D, substantially as set forth.

5. As an article of manufacture, the castshown in the drawings, adapted, when used in pairs or in sets of two or more, to consti tute a combined roller-chair and position-gage, substantially as herein described. 6. As an article of manufacture, the hereindescribed presser-rollerO,n1ade hollow at the ends and loaded or solid in the middle, whereby the desired size or diameter of roller is obtained without unnecessary weight of material, substantially as herein described.

In testimony whereofI have hereunto set myhand this 4th day of August, A. D. 1882.
